Status: Active Adaptive Management
Adaptive management (AM) combines management and monitoring, with the aim of updating knowledge and improving decision-making over time. We provide a guide for managers who may realize the potential of AM, but are unsure where to start. The urgent need for iterative management decisions, the existence of uncertainty, and the opportunity for learning offered by often highly-controlled captive...

Status: Active Capture-Mark-Recapture Science
Capture-Mark-Recapture (CMR) can be viewed as an animal survey method in which the count statistic is the total number of animals caught, and the associated detection probability is the probability of capture. The method involves capturing a number of animals, marking them, releasing them back into the population, and then determining the ratio of marked to unmarked animals in the population...

Status: Active Breeding Birds
Patuxent science expands our understanding of the ecological relationships between breeding bird communities and their habitats. For example, Patuxent scientists follow structured decision-making principles to optimize the management of fresh-water and salt-marsh habitats to benefit wetland bird communities. Following pioneering studies documenting the effects of forest fragmentation on...

Status: Active Survival and Recruitment of Common Eiders in the Gulf of Maine
The dresseri race of common eiders breed from central Labrador to southern Maine and winter from Newfoundland to Massachusetts. The breeding population in the mid-1980s was estimated to be 71,000 pairs, of those 40% were in Maine. In Maine, nesting eiders increased from a few pairs in the early 1900s to approximately 28,000 pairs in 1989. Although the number of birds seems to be stable, the...

Visualizing populations of North American sea ducks: Maps to guide research and management planning
North American sea ducks generally breed in mid- to northern-latitude regions and nearly all rely upon marine habitats for much of their annual cycle. Most sea duck species remained poorly studied until the 1990s when declines were noted in several species and populations. Subsequent research, much of which was funded by the Sea Duck Joint Venture...

A full annual cycle modeling framework for American black ducks
American black ducks (Anas rubripes) are a harvested, international migratory waterfowl species in eastern North America. Despite an extended period of restrictive harvest regulations, the black duck population is still below the population goal identified in the North American Waterfowl Management Plan (NAWMP). It has been hypothesized that...

Survival of female mallards along the Vermont–Quebec border region
Understanding effects of location and timing of harvest seasons on mortality of ducks and geese from hunting is important in forming regulations that sustain viable waterfowl populations throughout their range. During 1990 and 1991 we alternately marked 80 hatching year (HY), female mallards along the Vermont–Quebec border; half with radio-...

A multivariate assessment of changes in wetland habitat for waterbirds at Moosehorn National Wildlife Refuge, Maine, USA
We assessed changes in vegetative structure of 49 impoundments at Moosehorn National Wildlife Refuge (MNWR), Maine, USA, between the periods 1984-1985 to 2002 with a multivariate, adaptive approach that may be useful in a variety of wetland and other habitat management situations. We used Mahalanobis Distance (MD) analysis to classify the refuge?...

Macroinvertebrate abundance, water chemistry, and wetland characteristics affect use of wetlands by avian species in Maine
Our objective was to determine use by avian species (e.g., piscivores, marsh birds, waterfowl, selected passerines) of 29 wetlands in areas with low (<200 ueq 1-1) acid-neutralizing capacity (ANC) in southeastern Maine. We documented bird, pair, and brood use during 1982?1984 and in 1982 we sampled 10 wetlands with a sweep net to collect...

Effects of hunting on survival of American woodcock in the Northeast
Numbers of American woodcock (Scolopax minor) males counted on the annual singing ground survey (SGS) have declined over the last 35 years at an average rate of 2.3% per year in the Eastern Region and 1.8% per year in the Central Region. Although hunting was not thought to be a cause of these declines, mortality caused by hunters can be...

Phylogeography of the American woodcock (Scolopax minor): Are management units based on band recovery data reflected in genetically based management units?
Information on population connectivity throughout the annual cycle has become more crucial, because populations of many migratory birds are in decline. One such species is the American Woodcock (Scolopax minor), which inhabits early-successional forests in eastern North America. Although band recoveries have proved useful for dividing populations...

The role of pH in structuring communities of Maine wetland macrophytes and chironomid larvae (Diptera)
Aquatic vascular plants, or macrophytes, are an important habitat component for many wetland organisms, and larvae of chironomid midges are ubiquitous components of wetland fauna. Many chironomids are primary consumers of algae and detritus and form an essential energetic link between allochthonous and autochthonous primary production and higher...

Abundance and distribution of the common eider in eastern North America during the molting season
Like most other sea ducks, male common eiders (Somateria mollissima) concentrate in large groups to molt following the breeding season. Although Maine conducted surveys in the 1980s, little was known of eider molting sites in Atlantic Canada until recently, when surveys and research conducted in Quebec, Newfoundland, Labrador, Nova Scotia and...

Extraordinary size and survival of American black duck, Anas rubripes, broods
Two female American black duck, Anas rubripes, were initially observed during June 1982 with 20 Class Ib or 18-22 Class Ia-b ducklings in two wetlands in Hancock County, Cherryfield, Maine. Fifteen of 20 ducklings (75%) in one brood and 16 of 18-22 ducklings (72-89%) in the other brood survived to fledge. These large broods probably resulted...
